A new design for unifying the seven planetary archangels with sigils from the Heptameron and Agrippa.
In the very center of the sigil is a pentagram, symbolizing the unification of the four elemental forces of the universe, along with the fifth force of spirit. Immediately outside this are the seven astrological planetary symbols, representing each of the seven planets of classical Ptolemaic astronomy. Outside of these are the seven sigils of each of the planetary spirits, from Agrippa's second book, Celestial Magic. Outside of each of these, and in each point of the heptagram, are the sigils of the planetary intelligences, again from Agrippa's Celestial Magic.
